Engineered Nanoparticles in the Environment
Workshop on Engineered Nanoparticles in the Environment - Analysis, Occurrence and Impacts
19-20 October 2010 - Koblenz, Germany
The workshop was organised by the German Federal Institute of Hydrology (BfG) as part of the NORMAN programme of activities.
The workshop addresses, amongst others, issues related to analytical techniques for nanoparticles in environmental matrices, the fate of engineered nanoparticles in the aquatic environment and during wastewater treatment, their interactions with inorganic and organic pollutants as well as their potential ecotoxicological impacts on biota.
The main objective of the meeting was to discuss and evaluate the future requirements with regard to a profound environmental assessment of engineered nanoparticles. About 70 participants attended the workshop, with 14 oral presentations and 14 posters.
The conclusions of this two-day workshop were presented in the NORMAN Bulletin Issue N°2 (Workshop on Engineered Nanoparticles in the Environment: Analysis, Occurrence and Impacts).
